Keep : Home-workout and running platform with guided video courses and a social training community.

Keep launched in 2015 and has since signed up more than 300 million users, one of China's most-used fitness apps.

Users stream guided courses for strength, HIIT, yoga and running, track runs and rides on mapped routes, and follow diet guidance. Keep also sells exercise bikes, treadmills and smart rings.

A social layer adds group challenges and medal events that keep members active. The main app runs in Chinese for users in China, with a separate international edition available too.

Does Keep sell hardware?

Yes — smart bike, treadmill, dumbbells, and apparel, often priced below U.S. connected-fitness gear.

How does Keep pricing compare to Western fitness apps?

Keep offers a much larger free workout library than Apple Fitness+ or Peloton, covering running, yoga, strength, and dance. Premium costs about $2-5/month versus $10-13/month for Western rivals. However, content quality and production value are generally lower, and the social feed can feel cluttered.

How does Keep's AI form correction handle privacy?

Keep's AI uses camera-based pose estimation during workouts. According to their policy, video data is processed on-device and not uploaded unless you choose to share. However, the company has access to anonymized skeletal data for algorithm improvement.

Can I use Keep without a Chinese phone number?

Yes, the international version supports email registration and works outside China. However, some features (like local gym partnerships) are China-only.

How does Keep differ from Peloton or Nike Training Club?

Keep is more affordable (free tier available), more social (heavy emphasis on community sharing), and more integrated (combines training, nutrition, shopping in one app). It also has stronger AI personalization features.
